How to Generate API Documentation from Swagger Automatically

Most of developers use Swagger to document API automatically, it can provide your team or external collaborators with easy access to your API, enabling users to make accurate calls to your API. To reduce errors caused by manual documentation, many API developers prefer to find good ways to automatically generate API documentation.

In this post, we will provide you with a comprehensive guide on how to generate Swagger documentation for your API. Additionally, we will introduce a valuable tool called Apidog that can help streamline the documentation process.

What is Swagger?

Swagger, or the OpenAPI Specification, is an open-source framework used to define and document RESTful APIs. It provides a standard way of describing RESTful APIs that allows both humans and machines to understand the API's capabilities without accessing its source code, documentation, or network traffic.

Swagger documentation includes critical information about your API, such as endpoints, request and response formats, authentication methods, and more. This information is typically presented in a structured and easy-to-read format, making it an essential resource for developers who need to interact with your API.

How to Create API Documentation in Swagger?

After having a brief knowledge of Swagger, and how to write your API effectively and efficiently using Swagger, let's have a look.

Step 1. Create your new API by clicking the "+" button in the top left of the Swagger interface.

Step 2. Put all the necessary information here, such as owner, specification, template, visibility, etc. Please pay attention to your team organization.

Step 3. Select the OpenAPI specification that you desire. Select the "OpenAPI 2.0" and "OAuth 2.0 Access Code" here.

About the template, you can choose to generate API documentation from an empty document. However, if you are a beginner, Swagger also provides many templates for you. Just pick the one you prefer.  On the contrary, you can also customize the API documentation template for yourself.

Step 4. Generate Your New API Documentation in one click. You can get the documentation below. If you also want to export the Swagger documentation, click here to learn more.
